Sommario/riassunto

This title discusses a broad range of issues related to the use of computed tomography in geomaterials and geomechanics. The contributions cover a wide range of topics, including deformation and strain localization in soils, rocks and sediments; fracture and damage assessment in rocks, asphalt and concrete; transport in porous media; oil and gas exploration and production; neutron tomography and other novel experimental and analytical techniques; image-based computational modeling; and software and visualization tools. As such, this will be valuable reading for anyone interested in the appli
